Comfort  Must  Be  Built  In 

nrw  O  days  ought  to  be  set  aside  each  year  for 
the  planning  of  houses. 

One — the  coldest  day  in  winter,  when  you  can  see 
your  breath  in  the  north  bedroom  at  any  hour,  when 
sweaters  and  wraps  are  essential  to  even  partial 
comfort  and  the  coal  pile  is  the  only  thing  that  melts. 

The  other — the  hottest  day  in  summer,  when  the 
upstairs  rooms  resemble  bake  ovens,  when  sleep  is 
impossible  and  the  coolest  part  of  the  house  is  any¬ 
thing  but  comfortable. 

Primary  Purpose  Plan  yOUr  hoUSC  On  these  tWO 

of  a  Home  days  and  you’ll  not  lose  sight 

of  the  primary  purpose  of  a 
home — complete  protection  from  the  elements, 
and  genuine  comfort  the  year  round.  The  house 
where  inside  comfort  is  dependent  on  outside 
temperatures  can  never  be  a  satisfactory  home. 

For  years  we  have  been  paying  too  much 
attention  to  generating  heat  and  too  little  to 
keeping  it  where  it  belongs.  If  a  house  can’t  be 
kept  warm  we  say  the  boiler  is  too  small  or 
there  is  too  little  radiation.  If  fuel  bills  are 
twice  what  they  should  be  we  blame  the  quality 
and  price  of  coal. 


Comfort  Must  Be  Built  In 


This  photograph  of  a  Balsam- 
Wool  insulated  house  was 
taken  on  a  sub-zero  night.  While 
the  camera  man  made  his  exposure 
the  Balsam-Wool  representative 
went  inside  to  talk  to  the  owner. 
He  remarked  on  the  contrast  be¬ 
tween  the  weather  outside  and  the 
comfort  within  and  was  told  by 
the  owners  that — “We  never  have 
the  slightest  difficulty  keeping  the 


entire  house  at  just  the  tempera¬ 
ture  we  want  it.”  He  asked  about 
fuel  and  learned  that  the  owner 
had  checked  his  fuel  consumption 
with  a  neighbor  in  a  house  of  the 
same  age  and  somewhat  smaller  in 
size.  The  figures  revealed  a  23% 
saving  on  fuel  for  the  house  insulat¬ 
ed  with  Balsam-Wool.  “  We  credit 
this  difference  entirely  to  the  use 
of  Balsam-Wool”  said  the  owner.

And  all  the  time  the  heat  continues  to  seep 
out  through  the  walls  and  roof  just  a  little  faster 
than  the  overworked  furnace  can  generate  it. 

Enormous  Heating  experts  say  that  at  least 

Heat  Waste  one-third  of  the  heat  generated 

in  the  average  house  is  so  wasted. 
If  heat  waves  were  visible  like  flame  the  prob¬ 
lem  would  have  had  attention  long  ago. 

Only  in  the  past  few  years  have  scientists 
found  the  answer  by  applying  to  buildings  the 
principle  of  heat  insulation  around  which  house¬ 
hold  refrigerators  and  thermos  bottles  are  built. 

Itsimply  consists  of  placing  in  thewalls  and  roof 
of  a  house  a  material  which  is  a  natural  barrier  to 
the  passage  of  heat.  It  is  called  heat  insulation.

Balsam  Wool  in  the 

NE  of  the  most  interesting 
comments  of  approval  Bal¬ 
sam-Wool  has  received  is  that  from 
the  Arctic  Explorer,  Dr.  Donald  B. 
MacMillan,  which  is  reproduced 
on  this  page.  Dr.  MacMillan  used 
Balsam-Wool  to  line  the  small 
magnetic  observatory  used  in  his 
study  of  terrestrial  magnetism  and 
also  in  several  places  in  the 


North  Pole  Region 

“  Bowdoin.”  After  several  months 
in  the  Far  North  Dr.  MacMillan 
sent  the  above  radiogram  to  the 
Wood  Conversion  Company  from

Why  Every  House  Should 
Be  Insulated 

The  Need  for  It  is  not  intended  to  imply  here 

Insulation  that  everyday  life  in  the  unin¬ 

sulated  house  is  one  continual 
round  of  misery.  In  fact  the  weakness  of  the 
ordinary  house  is  most  apparent  in  the  little 
things.  You  see  it  in  the  way  the  family  keeps 
close  to  the  radiators  or  the  registers  on  a  cold 
winter  evening.  The  need  for  a  blanket  around 
the  house  is  apparent  in  the  frequent  need  for 
‘‘wraps”  and  sweaters  within. 

On  the  other  hand  the  old-fashioned  uninsu¬ 
lated  house  has  other  more  serious  faults.  The 
woman  who  has  to  make  three  or  four  round 
trips  to  the  coal  bin  on  a  cold  day  can  name  one. 
And  the  man  who  settles  with  the  coal  dealer 
can  name  another. 

Uniform  In  wiiiter  the  insulated  house 

Temperatures  holds  ill  the  heat  and  keeps  out 

the  cold.  In  summer  it  keeps 
the  heat  out.  In  terms  of  household  comfort 
insulation  means  comfortable,  uniform  tempera¬ 
tures  throughout  the  house  every  day  in  the  year.

You’ll  find  the  same  cozy  warmth  in  every 
room  that  you  formerly  found  only  in  spots. 
The  chair  near  the  window  becomes  as  popular 
as  that  near  the  radiator.  The  children  play  on 
the  floor  without  danger  of  catching  cold.  You 
invite  your  friends  in  for  the  evening  with  the 
assurance  that  they  will  be  genuinely  comfort¬ 
able  in  spite  of  the  raging  blizzard  outside. 


A  Photographic  Description  of  the  Insulation  Principle 


This  simple  little  test  was  made 
to  demonstrate  the  heat  stop¬ 
ping  properties  of  Balsam-Wool. 
The  box  at  the  left  is  made  of  one 
layer  of  standard  J^-inch  Balsam- 
Wool  nailed  to  a  wood  frame.  A 
52-lb.  cake  of  ice  was  placed  in  this 
box  and  another  cake  of  the  same 
size  and  weight  was  placed  on  the 


floor  beside  the  box.  The  temper¬ 
ature  in  the  room  was  kept  at  85  de¬ 
grees  Fahrenheit.  After^b  hours  the 
box  was  opened  and  the  picture 
shown  here  was  taken.  The  cakes 
were  then  weighed.  The  one  in  the 
insulated  box  weighed  27  pounds, 
the  one  outside  3^  pound.  No 
further  explanation  is  necessary.

People  who  live  in  insulated  houses  say  they 
never  knew  such  complete  comfort  was  possible. 
Four  or  five  degrees,  when  measured  by  the 
thermometer  on  the  back  porch,  are  insignificant. 
When  measured  by  the  mercury  on  the  living 
room  wall  they  represent  the  difference  between 
discomfort  and  comfort. 

Protection  Against  Undoubtedly  you  have  no- 

High  Winds  ticed  that  high  winds  can 

produce  discomfort  inside  a 
house  even  when  the  mercury  outside  does  not 
register  very  low.  Insulation  proves  a  barrier 
to  wind  by  sealing  up  all  the  cracks  and  crev¬ 
ices.  Some  insulations  are  more  efficient  than 
others  on  this  score  because  of  their  extreme 
flexibility  and  especial  attention  to  wind-proof¬ 
ing  qualities. 

Summer  The  joys  of  the  insulated  house  linger 

Comfort  long  after  the  snow  has  gone.  The 

blazing  heat  of  the  summer  sun  is 
stopped  at  the  roof  line.  Many  a  woman  in  an 
insulated  house  has  found  that  by  cooling  off 
the  house  during  the  night  or  the  early  morning 
hours  and  closing  it  up  as  the  mercury  rises  she 


7 


can  keep  the  entire  house  at  a  comfortable 
temperature  throughout  the  day. 

The  bedrooms  upstairs  and  even  in  the  attic 
stay  cool.  Some  say  that  getting  a  refreshing 
night’s  sleep  on  even  the  hottest  night  is  the 
greatest  boon  of  insulation. 

Fuel  Thousands  of  insulated  houses 

Savings  throughout  the  country  are  burning 

from  one-quarter  to  one-third  less 
fuel  than  neighboring  houses  of  the  same  size 
uninsulated.  Important  because  heating  cost  is 
the  biggest  single  item  of  expense  in  the  opera¬ 
tion  of  most  homes. 

The  owner  of  the  well  insulated  house  gets  a 
33^%  discount  on  his  fuel  bills  for  life.  If  this 
booklet  happened  to  arrive  in  the  same  mail 
with  one  of  your  fuel  bills  you  know  what  such 
a  saving  would  mean  in  your  case. 

Less  Heating  The  insulated  house  requires  less 
Equipment  heating  equipment.  Heating  en¬ 

gineers  recommend  a  reduction  of 
as  much  as  20%  in  boiler  capacity  and  radia¬ 
tion.  Thus  a  portion  of  the  insulation  cost  is 
offset  when  the  house  is  built.  The  balance  is 
paid  back  in  installments  with  the  coal  bills. 


8 


The  Health  The  insulated  house  is  a  more  health- 
ful  place  in  which  to  live.  Uniform 
temperatures  are  healthful  tempera¬ 
tures.  The  house  with  a  ‘‘jumpy”  thermometer 
is  apt  to  see  the  family  doctor  pretty  regularly, 
and  while  the  doctor’s  prescription  may  cure  a 
cold  how  much  better  not  to  have  had  the  cold. 

By  assuring  cool  sleep-inviting  bedrooms  in 
hot  weather  insulation  is  further  conducive  to 
good  health.  You  awake  in  the  morning  after 
a  night  of  sound  sleep  fit  and  fresh  for  the  day’s 
work. 

Less  Furnace  There  is  another  advantage  of 
Tending  insulated  house  that  will  ap¬ 

peal  particularly  to  the  woman 
whose  job  it  is  to  “mind  the  fire”  during  the  day. 
The  fire  in  the  insulated  house  requires  attention 
only  at  night  and  morning  except  in  the  sever¬ 
est  weather. 


No  Furnace  Forcing 
Less  Fire  Hazard 


Because  so  little  heat  es¬ 
capes  from  the  insulated 
house  a  slow,  moderate  fire 
is  all  you  need  to  keep  the  temperature  where 
you  want  it.  By  eliminating  furnace  forcing  you 
reduce  fire  hazard.  You  only  have  to  glance  at 


9 


the  newspaper  headlines  on  a  bitter  cold  day 
to  realize  the  menace  of  overheated  stoves  and 
furnaces. 


Greater 
Re-Sale  Value 


In  view  of  the  many  benefits  of 
insulation  it  is  superfluous  to  say 
that  the  insulated  house  is  easier 
to  sell,  should  the  occasion  arise.  The  advan¬ 
tages  are  too  obvious,  the  cost  too  reasonable 
and  the  saving  too  attractive  for  any  home 
buyer  to  ignore.  More  than  that,  insulation  is 
a  guarantee  that  your  house  will  never  go  on 
the  “black  list”  as  being  hard  to  heat  and  ex¬ 
travagant  of  fuel. 


Those  who  build  houses  for  sale  have  been 
quick  to  see  the  sales  value  of  Insulation, 
especially  in  those  sections  where  insulation  is 
better  known.  Many  such  builders  have  adopted 
insulation  as  standard  equipment  and  are  finding 
that  their  homes  sell  more  readily  than  before. 


As  the  benefits  of  insulation  become  more 
generally  known  and  as  more  and  more  home- 
seekers  ask,  “Is  it  Insulated,”  it  becomes  in¬ 
creasingly  difficult  to  dispose  of  the  uninsulated 
house  and  correspondingly  easy  to  sell  the  home 
where  comfort  and  fuel  economy  are  assured. 


10 


Which  Would  You  Pick? 


These  houses  were  built  from 
the  same  plans  by  the  same 
contractor  yet  there  is  a  vast  dif¬ 
ference  between  them.  The  one 
at  the  top  owned  by  Mr.  J.  G. 
Carr,  Aurora,  Illinois,  is  insulated 
with  Balsam-Wool,  the  other  is  not 
insulated.  According  to  Mr. 
Carr’s  report  of  his  first  winter’s 
fuel  saving  he  will  save  annually 


about  $30.00  on  his  coal  bills  as 
compared  to  his  neighbor’s.  Mr. 
Carr  also  saved  $29.00  on  his 
heating  equipment  as  a  result  ol 
having  insulated  his  house.  With 
a  $59.00  saving  at  the  end  ol 
the  first  winter  you  can  readily 
see  that  the  Balsam-Wool  in  Mr. 
Carr’s  house  will  pay  for  itself 
in  a  very  few  years.

Insulation  in Tem-  It  WOuld  be  a  mistake  to  as¬ 
perate  Climates  sume  that  the  advantages  of 

insulation  are  restricted  to 
the  more  severe  climates. 

As  you  travel  farther  South  you  find  more 
dread  of  summer’s  heat  than  winter’s  cold.  In 
these  sections  the  chief  purpose  of  insulation  is 
to  keep  the  heat  out. 

Furthermore  the  average  house  in  the  mild- 
winter  section  is  not  built  for  warmth.  Nor  is 
much  attention  paid  to  heating  equipment. 
When  a  cold,  raw  day  comes  along  there  may  be 
difficulty  in  keeping  comfortably  warm.  In  the 
insulated  house  a  little  heat  goes  a  long  way. 


Insulation  in  the  Warmer  Climates 


A  HOME  in  Pasedena,  Califor¬ 
nia,  insulated  with  Balsam- 
Wool.  Insulation  is  rapidly  gaining 
favorin  the  more  mild  climates, not 


only  for  its  hot  weather  comfort 
advantages  but  also  for  its  ability 
to  make  a  little  heat  go  a  long 
way  when  a  raw  day  comes  along.

Balsam  Wool — the  Ideal 
Insulation 

Examine  the  sample  of  Balsam-Wool  which 
you  received  with  this  booklet.  It  doesn’t 
require  a  knowledge  of  insulation  theories  to  see 
how  this  “wooly”  blanket  makes  a  house  proof 
against  heat,  cold,  wind,  dust  and  dampness. 


Baisam-Wool  The  resemblance  between  Balsam- 
Resembies  Wool  and  sheeps  wool  doesn’t  end 

oheeps  Wool 

with  appearance.  Actual  tests  on 
the  two  materials  reveal  the  fact  that  one  is 
practically  as  efficient  an  insulator  as  the  other. 

The  scientists’  explanation  of 
the  high  insulating  efficiency 
of  Balsam-Wool  can  be  reduced 
to  very  simple  terms.  They  begin  with  the 
statement  that,  next  to  a  vacuum,  “dead”  air 
is  the  best  insulator  known.  And  they  add  that 
air  is  “dead”  only  when  confined  to  cells  so 
small  that  it  cannot  circulate. 


The  Efficiency 
of  Balsam-Wool 


They  point  to  wood  as  a  natural  insulator, 
because  of  its  fibre  structure,  each  fibre  contain¬ 
ing  tiny  cells  which  constitute  “dead  air”  spaces. 
The  insulating  value  of  wood  is  well  known.

Balsam-Wool — Efficient  and  Practical 


At  the  top  is  shown  a  piece  of 
Balsam-Wool  with  the  paper 
coveringon  one  side  only.  Note  the 
resemblance  to  sheeps  wool.  And 
actual  tests  on  the  two  materials 


show  an  equally  striking  similarity 
in  insulating  efficiency.  The  other 
two  photographs  show  an  open  roll 
of  Balsam-Wool  and  a  sealed  roll 
ready  for  delivery  on  the  job.

Before  you  touch  the  metal  handle  of  a  hot  kitch¬ 
en  utensil  you  look  for  some  means  of  protect¬ 
ing  your  hand  but  you  do  not  hesitate  to  grasp 
the  wooden  handle  of  your  teakettle. 

A  Wood  Balsam-Wool  is  made  from  wood. 
Product  By  breaking  the  wood  down  into 

individual  fibres  and  rebuilding  these 
fibres  into  a  “wool”  form  the  number  of  air 
cells  is  increased  and  the  natural  insulating 
efficiency  of  wood  is  thus  multiplied  many  times 
over.  In  the  finished  product,  Balsam-Wool, 
these  fine  wood  fibres  and  dead  air  cells  present 
an  effective  barrier  through  which  heat  and 
cold  cannot  readily  pass. 

In  numerous  laboratory 
tests  Balsam-Wool  has  shown 
consistently  the  highest  insul¬ 
ating  efficiency  of  any  of  the  insulating  mate¬ 
rials  that  are  offered  in  competition  with  it. 

The  Equivalent  of  In  the  most  recent  test  on  Bal¬ 
sam-Wool  made  at  Armour 
Institute,  Chicago,  by  Pro¬ 
fessor  J.  C.  Peebles,  Balsam-Wool  was  given  a 
rating  of  5.5.  This  is  the  number  of  British  Ther¬ 
mal  Units  which  would  pass  through  a  one-inch

iod  with  the  temperature  on  one  side  of  the 
blanket  1°  F.  higher  than  on  the  other  side. 
This  rating  is  practically  the  same  as  that  of 
sheeps  wool;  thus  in  Balsam-Wool  you  have 
practically  the  same  insulating  value  as  you 
find  in  sheeps  wool  at  about  one-fifth  the  cost. 


Balsam- Wool  Saves  Fire  Loss 


The  fire-resistive  quality  of 
Balsam-Wool  was  well  demon¬ 
strated  during  the  construction  of 
the  Royal  Palm  Terrace,  Los 
Angeles,  California,  shown  above. 
Mr.  Charles  Sheblak  the  owner 
writes,  “during  the  process  of  roof¬ 
ing  an  asphalt  kettle  burst  into 
flame  which  spread  to  a  second 
kettle.  The  flame  shot  into  the  air 
15  feet.  The  heat  was  so  intense 
that  we  could  not  get  near  enough 
to  throw  sand  on  the  fire  and  the 


garden  hose  on  the  job  was  of 
little  use. 

“The  studding  of  the  lower 
floor  caught  on  fire  and  the  flames 
licked  the  Balsam-Wool.  After 
ten  minutes  the  fire  department 
arrived  and  put  the  fire  out. 
The  Balsam-Wool  blistered  and 
charred  but  did  not  burn.  My 
contractor  and  all  of  us  agreed  that 
if  Balsam-Wool  had  not  been  used 
there  would  have  been  little  chance 
to  save  the  building.”

Other  Qualities  of  Balsam- W ool 

It  is  not  enough  that  an  insulating  material 
show  a  high  record  of  efficiency  as  a  heat  insu¬ 
lator.  It  must  possess  practical  qualities  to 
protect  that  high  efficiency  and  keep  it  constant. 

When  you  sit  at  home  on  a  sub-zero  night 
enjoying  the  cozy  warmth  of  your  Balsam-Wool 
insulated  house  the  chances  are  you  will  not  be 
thinking  about  these  practical  qualities.  Yet 
that  comfort  which  you  prize  so  highly  is  de¬ 
pendent  to  a  considerable  extent  upon  them. 

Baisam-Wool  Examine  the  sample  of  Balsam- 

is  Waterproof  Wool  at  One  of  the  corners  and 

note  the  film  of  asphalt  which 
covers  every  inch  of  the  paper  on  the  inside. 
This  waterproof  coating  is  there  to  keep  the  wool 
dry  at  all  times.  Moisture  destroys  insulating 
value.  This  asphalt  coating  also  serves  to  keep 
dampness  out  of  the  house.  Balsam-Wool  in¬ 
sulated  houses  are  warm,  dry,  and  healthful 
even  in  the  damp  days  of  spring. 

Balsam-Wool  Oiice  in  place  in  the  walls  and

is  there  to  stay.  It  cannot  decay.

permanent  bond  between  wool  and  paper. 

Balsam-Wool  The  chances  are  the  Balsam- 

is  Fire-resistant  Wool  in  your  house  Will  never 

be  called  upon  to  stand  a  fire 
test.  It  is  a  comfortable  feeling,  nevertheless, 
to  know  that  Balsam-Wool  is  chemically  treated 
to  make  it  fire  resistant  and  that  you  are  not 
adding  any  fire  hazard  to  your  house  when  you 
insulate  it. 


Rat,  Mouse  and 
V  ermin-proof. 
Sanitary 


Experience  has  shown  that  Bal¬ 
sam-Wool  does  not  attract  rats 
or  mice.  Balsam-Wool  is  clean, 
sanitary  and  odorless.  Assurance  of  this  is 
found  in  its  rapidly  increasing  use  as  insula¬ 
tion  in  the  better  grades  of  household  refrigera¬ 
tors.  No  woman  need  worry  about  its  cleanli¬ 
ness  and  sanitary  qualities. 


Flexible— Easy  Balsam-Wool  is  light  and  fiex- 

to  Apply  ihle.  It  is  easy  to  apply  and  can 

be  fitted  quickly  into  corners 
and  around  projections.  The  temptation  to 
slight  the  hard  places  doesn’t  enter  into  a  Bal¬ 
sam-Wool  job.  It  comes  in  standard  widths

Balsam-Wool  insulation  is  with¬ 
in  the  reach  of  every  builder. 
The  material  itself  is  reasonable 
in  price  and  because  of  the  ease  with  which  it  is 
applied  the  installation  cost  is  low.  It  should 
be  remembered,  too,  that  whatever  you  spend 
for  insulation  will  be  returned  to  you  in  lower 
fuel  bills.

Balsam-Wool 


This  photograph  il¬ 
lustrates  vividly  the 
heatloss  through  theroof 
of  the  uninsulated  house 
and  suggests  the  need 
for  insulation.  It  was 
too  cold  outdoors  when 
this  photograph  was 
taken  for  the  snow  to 
melt  off  the  roof  of  the 
garage  which  is  not 
heated.  The  heat  loss 
from  the  house,  however, 
is  sufficient  to  melt  all  of 
the  snow  off  the  roof 
with  the  exception  of  a 
strip  over  the  eaves 
where  the  heat  coming 
through  the  roof  cannot 
reach  it.

Sound-deadener  OUtside  walls  of  yOUt  hoUSe 

with  Balsam-Wool  you  auto¬ 
matically  make  it  more  quiet  and  livable.  For 
Balsam-Wool  is  an  efficient  sound  deadener. 

Applied  in  the  inside  walls  and  in  the  floors 
Balsam-Wool  makes  the  whole  house  more  quiet 
and  each  room  more  private.

your  bath-room.  This  is  a 
simple  job  and  inexpensive.  It  is  a  good  plan, 
as  a  part  of  this  job,  to  wrap  the  soil  pipe  with 
Balsam-Wool  and  thus  deaden  much  of  the  noise 
which  would  otherwise  be  conveyed  to  other 
parts  of  the  house.

Nowhere  is  efficient  insula¬ 
tion  more  necessary  than  in 
household  refrigerators  and  rail¬ 
road  refrigerator  cars.  The  fact 
that  Balsam-Wool  is  being  used 
today  by  a  considerable  number  of 
leading  refrigerator  manufacturers 
and  car  builders  is  just  another 
indication  of  its  high  insulating 
efficiency.  A  number  of  Balsam- 
Wool  insulated  ice  boxes  are  illus¬ 
trated  on  this  page.  The  photo¬ 
graph  at  the  bottom  shows  a 
refrigerator  car  after  the  Balsam- 
Wool  has  been  installed.

What  Users  of  Balsam- Wool 
Say  About  It 

The  letters  and  comments  that  are  coming  in 
from  owners  of  Balsam-Wool  insulated  buildings 
are  adding  another  important  chapter  to  the 
story  of  insulation.  The  records  of  Balsam-Wool 
results  in  actual  buildings  are  adding  further 
proof  of  its  high  insulating  efficiency  already 
established  in  the  laboratory.  To  the  “can  do” 
of  the  scientist  has  been  added  the  “has  done” 
of  the  users.

the  North  Pole 


On  page  4  there  is  reproduced 
a  radiogram  from  Dr.  Donald 
B.  MacMillan  sent  from  Ref¬ 
uge  Harbor,  North  Greenland,  and  reporting 
satisfactory  service  from  Balsam-Wool  at  tem¬ 
peratures  ranging  from  30°  to  60°  below  zero. 


Letters  from  nearer  home  are  reproduced  in 
this  book.  Home  owners  tell  of  fuel  savings  and 
increased  comfort — realtors  report  greater  sala¬ 
bility — contractors  commend  its  ease  of  appli¬ 
cation  and  others  tell  of  its  sound  deadening 
qualities,  its  fire  resistance  and  its  advantages 
as  roof  insulation  for  houses  already  built.

This  photograph 
shows  Balsam-Wool 
being  applied  in  the  walls 
of  a  house.  The  17-in. 
width  fits  snugly  be¬ 
tween  the  studding. 
The  material  flanges  au¬ 
tomatically  as  it  is  ap¬ 
plied  and  these  flanges 
are  held  tight  against 
the  studding  and  plates 
by  means  of  lath  or 
nailing  strips.  Every 
crack  and  crevice  is  thus 
tightly  sealed. 


NO  matter  how  hot 
the  sun,  this  room 
will  always  be  comfort¬ 
able.  In  this  story-and- 
a-half  house  Balsam- 
Wool  is  applied  not  only 
between  the  studs  but 
also  between  the  rafters 
and  under  the  ceiling 
joists.  As  a  rule  it  is  im¬ 
possible  to  live  comfort¬ 
ably  in  such  rooms  in 
an  uninsulated  house  in 
the  summertime.  Bal¬ 
sam-Wool  makes  them 
as  cool  as  the  rooms 
below.

Where  and  How  Balsam-Wool 
Should  be  Applied 

Where  Balsam- Wool  Balsam-Wool  should  be  ap- 
Should  be  Applied  plied  in  all  four  walls  and 

the  roof  or  top  floor  ceiling. 
In  addition  there  are  several  other  places  where 
insulation  is  necessary. 

In  houses  with  only  a  partial  basement  the 
floors  over  the  unexcavated  portions  should  be 
insulated  to  keep  out  the  cold  and  dampness. 
The  sun  porch  floor  should  be  insulated  for  the 
same  reason.  Where  a  part  of  the  second  story 
extends  out  over  a  porch  Balsam-Wool  should  be 
applied  in  the  floor  of  the  room  so  extended.

Standard  ^  insulate  a  house  with  Balsam- 

Building  Material 

Wool.  Neither  special  work¬ 
men,  tools  or  methods  are  required. 

For  heat  insulating  or  sound  deadening  houses 
Balsam-Wool  comes  in  one  standard  form,  3^ 
inch  thick.  It  comes  in  three  standard  widths 
which  meet  all  building  construction  require¬ 
ments.  The  carpenter  buys  the  width  he  wants 
and  then  cuts  from  the  roll  for  length  only.

How  to  Specify  and  Obtain 
Balsam-Wool 


Your  Architect  Simply  tell  your  architect  that 
Will  Specify  you  wish  to  have  the  walls  and 

roof  of  your  new  home  insul¬ 
ated  with  Balsam-Wool.  He  will  take  care  of 
the  details. 


Complete  If  you  are  dealing  direct  with 

Specifications  contractor  see  that  Balsam- 

Wool  and  the  method  of  appli¬ 
cation  are  written  into  the  specifications. 


See  Your 
Lumber  Dealer 


Balsam-Wool  is  sold  today  by 
lumber  dealers  in  all  sections 
of  the  country.  If  your  dealer 
does  not  happen  to  have  a  stock  on  hand  he 
can  get  it  quickly. 

Balsam-Wool  carries  the  name 
of  an  organization  that  for 
more  than  sixty-five  years  has 
been  known  for  the  high  standard  of  quality 
maintained  in  all  its  products. 

On  every  roll  of  Balsam-Wool  you  will  find  the 
Weyerhaeuser  Forest  Products  trade-mark,  the 
maker’s  pledge  of  personal  responsibility.

Many  a  house  that 
can’t  be  kept  “com¬ 
fortably  heated”  needs 
only  a  few  rolls  of  Bal¬ 
sam-Wool  in  the  ceil¬ 
ing  or  roof  to  keep  heat 
from  leaking  through 
to  the  outdoors.

What  Balsam-Wool  Can.  Do 
for  the  House  Already  Built 


60  Percent  Goes  Once  a  housc  is  built  there 

Through  the  Roof  jg  no  way  to  Stop  the  heat 

leakage  through  the  walls. 
But  the  large  heat  leakage  through  the  roof  can 
be  stopped.  60%  of  the  heat  loss  in  the  aver¬ 
age  house  is  through  the  roof.  This  waste  of 
heat  and  fuel  can  be  prevented  easily  and  at 
low  cost  by  applying  a  blanket  of  Balsam- 
Wool  insulation  either  over  the  attic  floor  joists 
or  between  the  roof  rafters. 

Heat  Resistance  of  Exhaustive  tests  on  actual 

Various  Roofings  j-Qof  sections  show  that  the 

wood  shingle  roof  is  by  far 
the  best  natural  insulator. 


Note; — The  figures  below  indicate  the  amount  of  heat  (expressed  in 
British  Thermal  Units)  which  passed  through  roof  sections  of  various 
materials  during  the  one  hour  test  period.  The  figures  in  the  first  column 
show  the  heat  loss  through  uninsulated  roofs  of  different  materials.  The 
second  column  shows  the  amount  of  heat  loss  through  the  same  roofs 
when  insulated  with  Balsam-Wool.

One  thing  of  special  interest  to  all  home¬ 
builders  brought  out  by  these  tests  is  that  while 
heat  insulation  is  essential  even  with  a  wood 
shingle  roof  it  becomes  doubly  necessary  when 
materials  which  are  ready  conductors  of 
heat,  such  as  asphalt  and  the  metals  are  used 
for  roof  covering. 

Advantages  of  The  advantages  of  roof  or  ceil- 

Roof  Insulation  insulation  in  the  house  al¬ 

ready  built  are  the  advantages 
of  the  completely  insulated  house  only  in  a 
lesser  degree — warmth  and  fuel  savings  in  winter 
and  cool  comfort  in  summer.

How  to  Add  a  Many  people  who  have  attic 
Comf^table  space  say  they  wouldn’t  finish  off 

the  attic  rooms  because  they 
wouldn’t  be  livable.  No  one  will  deny  that  the 
average  room  under  the  uninsulated  roof — cold 
in  winter  and  stifling  hot  in  summer — is  little 
better  than  storage  space. 

By  applying  insulation  in  the  roof,  attic  rooms 
can  be  made  as  comfortable  as  any  part  of  the 
house.  This  means  a  lot  to  the  woman  who 
wants  an  extra  bedroom,  a  guest  room,  or  a  play¬ 
room  for  the  children. 


Baisam-Wool  is  the  If  you  liave  been  thinking  of 

Ideal  Material  for  jng^iation  as  Something 

Root  Insulation  ,  ,  ^ 

expensive  you  will  be  sur¬ 
prised  at  the  figures  your  lumber  dealer  and 
carpenter  will  quote.  The  entire  cost  of  insulating 
the  average  roof  with  Balsam-Wool  will  be  re¬ 
turned  in  the  fuel  savings  the  first  few  years. 


Not  a  There  is  no  need  to  shudder  at 

Remodelling  Job  thought  of  having  the  car¬ 

penters  in  to  insulate  the  roof. 
It  is  a  quick,  clean  job.  The  muss  and  fuss 
that  are  so  often  a  part  of  remodelling  do  not 
enter  into  roof  insulation.

Other  Uses  For  Balsam-Wool 

Garages  The  valuc  of  Balsam-Wool  as  a  heat 
insulator  and  a  sound  deadener  is  by 
no  means  limited  to  houses. 

In  the  garage  it  lessens  the  danger  of  freezing 
and  makes  heating  easier  and  much  less  costly. 
It  makes  starting  easier.  And  all  automobile 
manufacturers  and  mechanics  are  agreed  on  the 
harmful  effects  of  permitting  a  car  to  freeze  up. 

On  the  Farm  The  farmer  has  been  quick  to  see 
the  advantages  of  insulation  in 
providing  better  and  more  healthful  quarters  for 
his  live  stock.  Where  the  farm  building  is  to  be 
either  heated  or  ventilated  or  both,  insulation 
becomes  a  necessity.  In  a  barn,  poultry  house, 
or  a  hog  house,  Balsam-Wool  pays  for  itself  in 
the  better  health  and  increased  productivity  of 
the  stock.

Fuel  Waste 
A  National  Burden 

The  Nation’s  fuel  supply  is  not 
inexhaustible.  Some  day  there  must 
be  an  accounting.  Present  high  prices 
of  fuel  are  merely  an  indication  of 
how  serious  such  a  problem  can  grow 
to  be.  If  a  saving  of  one-fourth  to  a 
third  can  be  made  in  the  Nation’s 
annual  fuel  consumption,  the  supply 
will  last  just  that  much  longer.  If 
heat  insulation  can  perform  this 
miracle  then  it  is  a  conservation 
measure  of  vast  importance.  That 
is  why  we  say  consider  insulation 
when  you  build — for  your  personal 
profit  and  for  the  Nation’s  good.
